(Continued)

I couldn't understand very well your inputOutput() so simplified. I made 
the deg°min' (within <span id="cgdgmn"></span>) disappear when radians 
is clicked:

https://files.nyu.edu/emf202/public/js/spherical2.html

The code now is working OK, except that when it loads it gives this 
error message:

TypeError: document.getElementById("cbdgmn") is null

pointing to the inputOutput else if line. Sorry, but that's way beyond 
my comprehension. Why does it give this message only when loading and 
not afterwards? Please explain.

And I would prefer it by clicking Clear it didn't affect the radio 
buttons and the checkbox...

Now I have to start going through the message of PointedEars, who also 
provides many interesting ideas.
